Radio communication system and radio communication method

A radio communication system comprising:

• a plurality of movable bodies that support route diversity transmission using a plurality of radio communication lines for data transmission;
• and
• an integration controller configured to collect line states of the radio communication lines for each of the plurality of movable bodies,
• wherein the integration controller is configured to transmit a control signal of the radio communication line to a particular one of the movable bodies so as to increase a number of the movable bodies in which a number of the radio communication lines whose line states satisfy a quality determination criterion is greater than or equal to a predetermined value, based on the line states of the radio communication lines collected for each of the plurality of movable bodies, and
• the particular one of the movable bodies is a movable body using a same radio communication line as another of the movable bodies, in which the number of radio communication lines whose line states satisfy the quality determination criterion is smaller than the predetermined value, among the movable bodies in which the number of radio communication lines whose line states satisfy the quality determination criterion exceeds the predetermined value.
